Privacy policy: punnet

Last updated: 9 November 2026

Short version: punnet keeps everything on your device. There is no server, no account, no analytics and no tracking. We never see your data.

What punnet does with data

Everything punnet remembers is saved in chrome.storage.local in your own browser. It does not use chrome.storage.sync, so nothing syncs to other devices.
punnet makes no network requests of its own. There is no analytics, telemetry, crash reporting, remote font or remote code.
There is no punnet account and no sign-in.
punnet does not read your cookies, passwords or tokens, and does not call Facebook's APIs.
punnet never sends a message. A message starter only puts your text into the message box on the page. You read it and press Send yourself.
Your home suburb is never sent anywhere. Distances are worked out on your device from a suburb table bundled inside the extension.

Listing details are read from the page you are already viewing, on your device. They are saved only in the items above.

Deleting your data

Use Clear and Restore all in the Filters sheet to wipe the stored lists. Removing the extension deletes everything it stored.

Permissions

punnet uses the storage permission to save the items above, the declarativeNetRequest permission to open Marketplace instead of the Facebook feed, and access to facebook.com so it can run on Marketplace pages.

Third-party data

Australian place data comes from GeoNames and is bundled inside the extension under CC BY 4.0. It is never downloaded at run time.

Not affiliated with Meta

punnet works with Facebook Marketplace through your own login. It is not affiliated with or endorsed by Meta. Facebook's own privacy policy applies to what you do on Facebook.

Selling or sharing

We do not sell, share, transfer or use your data for any purpose, because we do not have it.

Changes

If this policy changes, the date above changes and the new version ships with the extension update.
